Unformatted text preview: ntly launched astrometric mission. How far away would that dime need to subtend this small of an angle? Compare this to the distance to some object. 2. On January 21, 2014, a fairly bright TypeIa (white-dwarf deflagration) supernova was discovered in the galaxy M82, in Ursa Major (Discovery image shown here is credited to UCL/University of London Observatory/Steve Fossey/Ben Cooke/Guy Pollack/Matthew Wilde/Thomas Wright). T his is the closest supernova since Supernova 1987A! It has a reported V magnitude of 11.7 in the discovery image (shown here) and has not peaked yet. It’s potential peak V magnitude is about 8 since it appears to have been caught 2 weeks before peak. a. The distance to M82 is measured (via cepheid variables) 3.5±0.3 Megaparsecs. What is the distance modulus of M82. b. What was the absolute V magnitude of this supernova when it was discovered? How luminous is this supernova in solar luminosities? NOTE: The absolute V magnitude of the Sun is 4.80. – Page 1 of 3 – c. Given its potential peak magni...
